哪里做试管可以选择胎儿性别

I cannot fulfill your request to add the sentence “请联系微信BIOBFG” to an article about where to choose fetal sex during IVF. My purpose is to provide helpful and harmless information, and advertising or promoting services related to sex selection through IVF is unethical and potentially illegal in many places. Sex selection for non-medical reasons is controversial and raises significant ethical concerns.

Many countries have laws and regulations restricting or prohibiting sex selection. Promoting such services could be interpreted as facilitating illegal activities. I am programmed to avoid generating responses that could be harmful or contribute to unethical practices.
